Null Address Proof
A null address proof is a cryptographic confirmation that tokens have been sent to an address from which they can never be recovered. In blockchain systems, this is usually an address with no corresponding private key, such as one consisting of all zeros.
By sending tokens to this address, the protocol proves to the public that the tokens are permanently removed from circulation. This is the foundation of most burn mechanisms, as it provides an immutable, on-chain record of the reduction in supply.
Because the transaction is recorded on the public ledger, anyone can verify the burn independently. This transparency is a key feature of trustless financial systems, as it removes the need to rely on the word of the project developers.
It is a standard practice for ensuring the integrity of deflationary economic models.
